Hey guys, love the program, but I'm having some issues. I've managed to get OBS to capture games like Bastion and Doom II easily enough using Game Capture, but when I try something like Portal 2 or Diablo III, I can't get anything more than a black screen with audio. I also tried Window Capture but it was very choppy. Here's the build on the computer I use for this:

Intel Core i5-4570 3.2GHz Quad-Core
MSI B85M-G43 Micro ATX LGA1150
Corsair Vengeance 8GB (2 x 4GB) DDR3-1600
Seagate Barracuda 1TB 3.5" 7200RPM
MSI Radeon HD 7850 2GB
NZXT Tempest 210 ATX Mid Tower
Corsair 600W ATX12V
LG GH24NS95 DVD/CD Writer
Asus VS229H-P

And the contents of my latest log:

Re: Black screen w/audio

Is this a log from an attempt to capture Diablo III or Portal 2 with game capture?

Re: Black screen w/audio

This is from Portal 2, this morning before I made the thread. Sorry, I should've mentioned that before.

Re: Black screen w/audio

It doesn't really look like it's attempting to capture.

Try setting a capture hotkey instead of selecting the game from the dropdown, and then go in-game and press the hotkey and see if that works.

Are you using any overlay programs of any sort?

Re: Black screen w/audio

Holy crap, I think that worked. I may have tried that before, but apparently I was pressing the hotkey (I have it set to F11) BEFORE I started the stream. Simple mistake. Thanks so much for your help!
